Bug ID: 58670
Summary: Replace SXSSFRow's implentation of SXSSFCell[] storage
with a TreeMap<Int, SXSSFCell>
Product: POI
Version: 3.14-dev
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P2
Component: SXSSF
Assignee: [email protected]

>From dev mailing list [1]
Replace SXSSFRow's data structure for storing SXSSFCells with a TreeMap, which
uses less memory than an Array for sparse spreadsheets, reduces the number of
lines of code, and is faster for some methods (trivially slower for others).
Since the purpose of the streaming workbook API is to have a lower memory
footprint and not speed, this seems like a good tradeoff.
